The prefix row placement is common to RTL839x and RTL930x, but where an IPv6 entry sits is not: an RTL839x PIE rule matches a whole IPv6 destination in any row, while an RTL930x entry spans three rows and may only start on two rows of every eight. otto_l3_v6_row() and otto_l3_v6_slot() chose between the two layouts through use_l3_tables, which says how a family routes, not how its table is laid out. Give the families v6_slot_to_row() and v6_row_to_slot() and move each layout next to its row mover. Ordering, insertion, compaction and the capacity and IPv4/IPv6 collision checks stay common, and keep calling the same two helpers, which now ask the family. The common code calls them only for a family with a row mover. The formulas move unchanged. Built on the host from l3.c as it is, the placement code before and after this change maps every slot and row of both layouts alike, and runs 160000 random IPv4 and IPv6 insertions and removals, past a full table on both families, with the same rows and the same moves; a one-line mutation planted in each of the four callbacks makes the results differ. On an HPE 1920-48G (RTL8393) an IPv6 test round passes 20 of 20 checks, among them a /48 and a /64 inserted in both orders and IPv4 and IPv6 routes side by side, the routes of those checks forwarded in hardware to the right gateway. RTL930x is compile-tested only.

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:
Development
To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.8+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.
